    • A pump has a pump barrel formed from a larger diameter section and a smaller diameter section. Each section has a biased piston moveable within the section and the pistons are connected together to form a variable volume chamber between the pistons. As the connected pistons move toward the larger diameter section, a volume of fluid is moved through an inlet valve into the variable volume chamber of increasing volume. When the pistons are moved toward the smaller diameter section, a differential volume of fluid is discharged from the variable volume chamber of decreasing volume through a discharge valve into a discharge conduit. The pistons are actuated to move within the pump barrel by application and release of pressure at a remote end of the discharge conduit.
    • 泵具有由较大直径部分和较小直径部分形成的泵筒。 每个部分具有在该部分内可移动的偏置活塞,并且活塞连接在一起以在活塞之间形成可变容积室。 随着连接的活塞朝向较大直径部分移动,一定体积的流体通过入口阀移动到增加体积的可变容积室中。 当活塞向较小直径部分移动时,不同体积的流体通过排放阀从减小体积的可变容积室排出到排放管道中。 通过在排出管道的远端施加和释放压力来致动活塞以在泵筒内移动。

    • A flexible tube 20 has an inlet side fixed end 21, and an outlet side fixed end 22, and an elastic deformation portion 23 is provided between them. The elastic deformation portion 23 is provided with convex arc portions 42. In the convex arc portions 42, three apices 41 provided apart at approximately regular intervals in the circumferential direction are each curved in a convex shape outward so as to have smaller curvature radius than that of a virtual circle S tangent to the apices 41 from each apex as a center for deformation. Concave arc portions 43 are formed consecutively between the respective convex arc portions 42 in circumferential direction, and the concave arc portions 43 are each curved in a concave shape outward. At a time of expansion and shrinkage of the elastic deformation portion, the respective convex arc portions 42 elastically deform in the circumferential direction, and the concave arc portions 43 elastically deform in the radial direction.
